Complaint Review: SOS Self Defense Tools

Had an email from Science Of Skill (SOS) Slef Defense, and since I'm a mber of USCCA and other self defense groups, I didn't question it. The email had an offer for a fixed blade knife and pearl handled spring stiletto from Steel River Defense, free, just pay S/H of $9.95. I took the offer, placed the order and a few weeks later I received the products, which were nice quality. A few weeks after that I noticed a charge on my bank statement SOS SELF DEFENSE T 888 7296151, for $57. I contacted the number and got a generic AI voice recording stating their business hours of 9-5 EST and "all operators are busy, leave a message" etc etc. I left multiple messages with no response. So I did a Google search for SOS Self Defense unknown charge, and here we are. I have contacted my bank and placed a stop charge on it and hopefully cancel future charges.
